I just extracted a raw h264 stream from an .mp4 file using mp4box and used h264_parse to check a file I encoded with 708145's ELDER program to see if it was working correctly. But I found a section of the logfile that had something called "Copyleft 2005". I've heard of "copyright" but I 've never heard of a copyleft before.


Here is the excerpt from the logfile.

"string is ".E....H..,. .#..x264 - core 44 svn-438 - H.264/MPEG-4 AVC codec - Copyleft 2005 - http://www.videolan.org/x264.html - options: cabac=1 ref=5 deblock=1:0:0 analyse=0x3:0x133 me=umh subme=6 brdo=1 mixed_ref=0 me_range=20 chroma_me=1 trellis=0 8x8dct=1 cqm=0 chroma_qp_offset=0 slices=1 nr=0 bframes=3 b_pyramid=1 b_adapt=1 b_bias=0 direct=2 wpredb=1 bime=1 keyint=240 keyint_min=25 scenecut=40 rc=2pass bitrate=1169 ratetol=1.0 rceq='blurCplx^(1-qComp)' qcomp=0.60 qpmin=10 qpmax=51 qpstep=4 cplxblur=20.0 qblur=0.5 ip_ratio=1.40 pb_ratio=1.30."

The orginal logfile is too large to post


Is this an inside joke perhaps?

the GNU way of the copyright concept... basically the GPL license

type "define: copyleft" on google for more info: http://www.google.com/search?hl=en&q=define%3A+copyleft&btnG=Cerca+con+Google&meta=

I always knew it is an opposite to copyright, but as a joke, never thought it is a legit term. ;)
